WATER-COOLING- APPARATUS.

Application filed December 14,1927. Serial No. 239,982.

This invention relates to improvements in water cooling apparatus in which the water to be cooled passes through a plurality of pipe coils arranged in a refrigerating chamber.

In certain lines of endeavor, amongst which may be mentioned the baking business, it is essential that a supply of water be constantly on hand of a certain degree of coolness, and any variation from this certain degree of temperature affects not only the working of the bread sponge but also theguality of the ultimate product. The obects of the present invention are, therefore,

first, to provide a refrigerating chamber adapted to contain a cooling liquid in which the pipe coils are immersed; second, to provide means whereby the pipe coils are supported in the chamber spaced from the bottom thereof and from each other, so per mitting a free circulation of the cooling liquid through and around the coils; and third, to provide storage means for the cooled water so connected with the pipe coils 2 as to compel a constant circulation of the water through the said pipe coils and storage means and so ensure an even temperature of all the water in the system;

With these and certain other objects in view which will appear as the description proceeds, the invention resides in the novel construction, arrangement and combination of parts hereinafter first fully described in the following specification and later more specifically pointed out in the appended had to the drawings formin part hereo in which similar characters 0 reference indicate similar arts thrpughou't the different views, an in which Fig. 1 is a side elevation of the apparatus with portions of the sides of the cooling chamber and storage tanks removed to show the interiors thereof.

i Fig. 2 is a'top plan view of the apparatus with portions of the to s of the cooling chamber and storageta removed. Fig. 3 is a fragmentary sectional elevation of the cooling chamber and water coils showing how the said coils are supported in the chamber. r

Fig. 4 shows one of the supportingmembers'apart from its connection with the coils. In the drawings A indicates the cooling the storage tank.

.- 56 chamber of'the apparatus as a whole and B casing and container is filled with a suitable insulating medium 9, such for instance as cork.

or coils of any of the Well known automatically controlled electrically operated types. These coils are shown in the-present disclosure as projecting into the container 5 at points adjacent the opposite corners of the same and sufficiently below the-top of the ,said container as to be completely immersed in the liquid therein.

The number of refrigerating coils used determines the capacity of the installation, and this number may range from one upward, but when two are used the position shown is desirable as tending to give a more even cooling of the liquid in the tank-and a better circulation of the said liquid through and around the'said pipe coils.

The storage tank B is preferably of double 10 and 11 indicate refrigerating members construction, that is to say, it is formed with to tank 12 within a tank 13 of sufficiently larger dimension to afford an air space 14 -between the two, the inner tank resting upon supports 15' upon the bottom of the tank 13 or i being otherwise suitably supported therein. j i

16 indicates the inlet pipethrough-which water to be cooled is admitted to the system. The pipe 16 may connect with any suitable source ofwater supply under pressure, such for instance as a city water works system,

and it leads directly into the tank 12 at the top thereof, thewater discharged fromit being indicated by the numerals 17 18 indicates a'valve in the pipelfi which; is normally open but which may be closed to cut off the water supply in case of accident to any part of the apparatus.

19 indicates an outlet pi e leading from the upper part of the tanfi 12 to connect with the member-'20 of the uppermost of the pipe coils in the container A. From the pipe 20 the water passes by way of the return elbows 21 and the pipes 22, 23, 24 25, 26 and l into the tank 12 at the point 32 adjacent the bottom thereof.

33 indicates affrost resisting liquid, pref-'.

erably a mixture of alcohol and water, commonly called a brine7, with which the container is filled to completely submerge the refrigerating coils 10 and 11 and the pipe coils.

4 receive the sides of the members 34 indicates as supporting member, several; of which may be used to support the lower most of the pipe, coi-ls space from the bottom pf the container 5, andothers of which maybe used to support the pipe coils above from eachother, this being best shown in Fig. 3.. supporting members serve to maintain the several pipe coils inhorizontal position while permitting" a free and unobstructed circulation of the cooling mixture under, through and around'the said coils. The members 34 maybe made depressionsin their sides properlyspaced'to eral pipe coils.

. The members The outlet or service pipe 36 noted, draws from a point adjacentthe bottom of the tank-12, so that the coldest water in the system will flow from the saidpipe when the valve 37 is opened.

The action of theliquid 33 inthe con tainer 5 under the influence of the refrigerating coils 10 and 11 is too well understood to 'requiremuch in the way of explanation, suiiice it to say however, that a constant rise and fall or circulation of the said, liquid through and around the pipe coils in" the container is set up by the influence of the refrigerating coils, the cooled liquid gravitatin to the bottom of the container and absor ing the heat from the water in the Pin rom some easily manipulated metal bent to form loops and providing a series of semi-circular v of the sev-" a I sbrption of heat from the outside atmos- 34 may be all alike and in: terchangeable as to their positions in construction.

pipe coils on its return journey to the refrigerating coils.

The action of the water 17 in the system is precisely similar to that described for the liquid 33. Asthe water in the pipe coils is cooled by action of the liquid 33 and its specific gravity is increased it passes down 'through'the pilpe coils'and, by way of the pipe 30, is disc arged into the lower end of the tank 12, thus displacing the warmer and lighter water above which passes out of the tank and, byway of the pipe 19, reaches the member 20 of the pipe coils. As the circulation of the water is continuous it will be seen that but a very short time is required to bring, all of the waterin the system to an approximately even temperature, at which desired temperature, the thermostatic control feature of the refrigeratingapparatus comes into operation to retain the water at the desired temperature.

Upon-the periodical withdrawal of water from the system by operation 0f-the valve 37,'and the, replacement of the .same takes place by, way of the pipe 16, the automatic control, always present in such systems of refrigeration, can be relied upon to again permit the full operation of the refrigerating coils to quickly cool the more rapidly circulating water in the pipe coils.

The insulated construction of the cooling phere by the liquid therein.

The provision of. the tank B assures an r ample supply of cooled water at all times, it' will 'beand at the game time ensures the circulation of the ter through the entire system; two very desirable features;

Having thus fully described my said invention, what I claim is* i Water cooling apparatus comprising a suitably insulated container, a frost resisting liquid in the container, pipe coils immersed in the liquid, a refrigerating element immersed in the liquid above the-pipe coils, a storage tankfor water, a pipe'connecting the upper end of the tank with the uppermost of the pipe coils, and a pipe connecting the lowermost of the pipe coils with the lower portion of the tank.
